emdr therapy in young children, a double-blinded randomized controlled trial

Conditions: Trauma, Psychological; Stress, Psychological; Anxiety Disorders

Summary: this project aims to answer to the question of emdr effectiveness in young children and to determine whether or not the therapy effectiveness is related to the level of cognitive functioning in young children. the study requires a total of 60 children, girls and boys, aged 3 to 6 years and presenting disorders related to stressors, anxiety and/or trauma. participants will be randomly distributed in two groups: "emdr therapy" (n=30) group or "control therapy" (n=30) group. the study will take place in four stages: 1/ pre-treatment phase : an evaluation of child's various cognitive and executive functions, child's symptomatology and parental distress is planned in a pre-treatment phase. 2/ treatment phase : an emdr therapy or a routine care is administered to the child between 6 to 10 weeks. 3/ post-treatment phase : a reassessment of child's and parent's symptoms is planned at the end of treatment. 4/ continuation of treatment: children who have received control therapy and without symptomatic improvement will be proposed emdr treatment. these children will receive the same symptomatic assessments at the end of emdr treatment. a significant reduction in disorders related to trauma or stress and anxiety factors and their symptomatology, as well as comorbid disorders and their symptomatology, is expected in children who received emdr therapy compared to the group who received a control therapy. these results are expected to be robust over a period of at least 3 months. the positive effects of emdr on child symptomatology are also expected to be more pronounced in children showing higher levels of cognitive functioning

eye-movement desensitization and reprocessing (emdr) therapy is now recommended to anyone suffering from emotional disturbance related to psychological trauma, including babies and very young children. results of this therapy are promising in young children for ptsd and its comorbidities. however, no studies have documented yet the specific effects of individual emdr therapy in the 3-6 years children. the question of the emdr effectiveness in this population should be investigated first to meet the therapeutic needs in the care management of childhood psychotrauma, and secondly because emdr therapy involves memory and executive functions that are very immature in children under 6 years old. indeed, emdr involves therapeutic methods such as cognitive restructuring which requires that certain executive functioning components to be functional, even those processes are still developing in young children. emdr also involves an exposure in the imagination that solicits episodic memories, whereas the ability of young children to retrieve thoses memories is very limited compared to that of adults. finally, the alternating bilateral stimuli used in emdr would have an effect on autobiographical memory. however, an infantile amnesia is observed between the ages of 2 and 6, with an absence and then a poverty of autobiographical memories. therefore, the present project aims to answer to the question of emdr effectiveness in young children suffering from stress related disorders, anxiety and/or trauma, but also to determine whether or not the therapy effectiveness is related to the level of cognitive functioning in young children. this study requires a total of 60 children, girls and boys, aged 3 to 6 years and presenting disorders related to stressors, anxiety and/or trauma. participants will be randomly distributed in two groups: "emdr therapy" (n=30) group or "control therapy" (n=30) group. the study will take place in four stages: 1/ pre-treatment phase : an evaluation of child's various cognitive and executive functions, child's symptomatology and parental distress is planned in a pre-treatment phase. 2/ treatment phase : an emdr therapy or a routine care is administered to the child between 6 to 10 weeks. 3/ post-treatment phase : a reassessment of child's and parent's symptoms is planned at the end of treatment. 4/ continuation of treatment: children who have received control treatment and without symptomatic improvement will be proposed emdr treatment. these children will receive the same symptomatic assessments at the end of emdr treatment. in terms of results, a significant reduction in disorders related to trauma or stress and anxiety factors and their symptomatology, as well as comorbid disorders and their symptomatology, is expected in children who received emdr therapy compared to the group who received a control therapy. these results are expected to be robust over a period of at least 3 months. the positive effects of emdr on child symptomatology are also expected to be more pronounced in children showing higher levels of cognitive functioning. this protocol represents the first randomized controlled trial to investigate effects of an individual emdr therapy conducted specifically in children aged 3 to 6 years.
